Operational tab

The Operational tab contains operational data on Projects, Transmission Lines and Substations. To access this, select the entity on the map or in a table, then select the Operational tab in its side panel.

Top controls

The controls above the charts set the time period for every chart in the tab, and are synced with the global time picker, so changing one updates the map and the other too.

• Group by sets how values are grouped along the chart: Time of day average, or a fixed granularity like half-hour, day, week, month or year.
• Time of day average shows the average value for each time of day, based on all the data in your selected period. Choosing a granularity instead shows the actual value for each step across the period.

Reading the charts

Each chart shows one or more series over the selected time period. Click and drag across a chart to zoom into that period, or use the reset arrow to return to your original range.

Below the chart, a summary section shows each series’ total or average for your selected period.

Hover a datapoint on the chart to see the summary switch to just that point’s values.

Project charts

• Energy shows dispatched output alongside curtailment, so you can see how much energy was curtailed against what was actually generated. For a project with more than one DUID, the data shows the sum of all the DUIDs. Learn more.

  

• For battery projects, Energy shows discharging alongside charging (energy drawn from the grid). Learn more.

  

• Spot Revenue shows net spot revenue and missed revenue from curtailment. Learn more.

  

• For batteries and pumped hydro, Spot Revenue shows Discharging Revenue (energy sold, positive) and Charging Revenue (energy bought, negative) separately, rather than netted.

  

Transmission line charts

• Line flow shows power flow along the line, in two colours by direction. Orange is flow towards the line’s end substation, and cyan is flow towards its start substation. The summary table below the chart names the substation each colour is flowing towards, and shows flow as a % of the line’s rating alongside the normal and emergency ratings. The chart shows flow in MVA where it’s available, and falls back to MW otherwise. Learn more.

  

  Note: When the Headroom operational visualisation is selected, flow direction is also shown on the map as animated chevrons travelling along the line.

• Headroom shows the room left on the line once its rating, flow and enforced network constraints are taken into account. The green line is the average, and the shaded bands show how low it got (the worst 1%, 5% and 10% of half hours). Learn more.

  

• Marginal Value of Constraints shows the as-bid value of one additional MVA of line rating over time. The table below it shows the total for the period. Learn more.
